SPECIFICATION forming part of Letters Patent No. 323,354, dated July 28,1885,

Application filed March 25, 1885. (No niodei.) Patented in GermanyFebruary 3, 1882, No; 19,305.

To all whom it may concern:

in it known that I, JOHANN H. MULLER, of Gravesend, in the county ofKings and State of New York, have invented a new and Improved Gar Brakeand Starter, of which the following is a full, clear, and exactdescription.

This invention relates to certain new and useful improvements in thatclass of car brakes and starters in which springs are brought in tensionby the brakeshoes, and the power in the springs is then utilized instarting the car.

The invention consists in the construction and combination of parts anddetails, as will be fully set forth and described hereinafter, andpointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a car-truck providedwith my improved car brake and starter. Fig. 2 is a plan view of thesame. ig. 3' is an end view.

The wheels A are rigidly mounted on the axles 'B, and adjacent to theinner side of each wheel two ratchet-wheels, G and D, are rigidlymounted on each axle, the teeth of the two rutchetwheels projecting inopposite directions. The wheels 0 have a greater diameter than thewheels 1). The brake-shoes E are hinged to sliding pieces I at the endsof side bars, F, between the two wheels on each side, and which bars arepivoted at their middles on a shaft, J, held by hangers G, secured toand projecting downward from the side bars of the truck-trains II. Thesliding pieces I are preferably made wedge-shaped and arranged inwedgeshaped grooves in the bars F. The slides I are connected bytoggle-levers K with the ends of sliding sleeves L on the shaft J, andbetween the inner ends of the sleeves L connected elliptical or ovaldisks M are pivoted centrally on the shaft J, and are connected atopposite ends with the bralterods P, which are operated by the usualbrake-shafts or other devices.

Spiral springs N surround the shaft J between the ends of the sleeves Land the bars F, and press the sleeves toward each other. The slides I onthe opposite sides of the truck are connected by rods or bars 0. To eachend of l each bar 0 two cords or chains, Q and Q, are secured, the cordor chain Q, passing over pulleys R on the truck-frame to one wheel A onone side, and the cord or chain Q passing over pulleys R on thetruck-frame to the other wheel A on the same side. Ratchet-bars S aresuspended from the ends of the cords or chains Q adjacent to the edgesof the ratchetwheels D, and ratchet-bars S are secured on the ends ofthe ropes or chains Q adjacent to the rims of the wheels G. Powerfulsprings T are secured to the side bars of the truck, and their free endsrest upon the ends of the bars 0 and press downward.

The operation is as follows: When the car runs in the direction of thearrow a, and is to be stopped, the disks M are turned by means of veachrod 1 and press the sleeves L toward the sides of the truck-frame, andby means of the toggle-levers K the shoes E are pressed against thewheels A, whereby the rear brake-shoes are pulled downward and thefrontshoes are pulled upward, and thereby the bars F are inclined, andthe ends of the springs T resting on the front bar 0 are raised and thesprings brought in tension, whereby the ratchet-bars S are lowered andin position to engage with the ratchet-wheels D. The car has beenstopped by this time. Then the disks M are turned back in the positionshown in Fig. 2, the sleeves L pushed toward each other by the springsN, whereby the brakcshoes E are moved from the wheels, and then the freeends of the springs T can move downward and press down the front bar 0,thereby pulling up the ratchet-bars S, which engage with theratchet-wheels C and revolve the wheels in the direction of the arrow1), and thus propel the car in the direction of the arrow (1/. \Vhen thecar runs in the inverse direction of the arrow (1/, the ratchetwheels I)and ratchet-bars S are used in the manner described above.

Having thus described myinvcntion, I claim as new and desire to-secureby Letters Patent- 1. The combination, with a cartrneh, of a leverpivoted at its center at each side of the car and between the wheels atthe said side of the car, slides on the ends of the levers, andbrake-shoes pivoted to the said slides, substantially as herein shownand described.

2. In a car brake and starter, the combina- "tion, with the swingingbars F, mounted on a shaft, J, and bars 0, uniting the bars F, of thesliding brake-shoes E, the toggle-levers K, the sleeves L, devices formoving the sleeves from each other, the springs T, resting on the bars0, the ropes or chains Q Q, connected With the bars 0 and passed overpulleys It It,

the ratchet-bars S S on the ends of the ropes or chains, and theratchetwheels O D on the shafts, substantially as herein shown anddescribed.

4. In a car brake and starter, the combination, with the shaft J, of thebars F, the bars 0 uniting them, the sliding brake-shoes E, thetoggle-levers K, the sleeves L, the springs N on the shaft J, thesprings T, secured on the trnck-fra1ne and resting on the bars 0, theropes or chains Q Q, the pulleys R R, the ratchet-bars S S, and theratchetwheels (J D on the axles, substantially as herein shown anddescribed.
